Crown expert maintains alleged murderer Richard Henry Bain acted out of anger

MONTREAL — The Crown's expert psychiatrist has concluded his testimony at the murder trial of the man charged in the shooting on the night of the 2012 Quebec election.

Joel Watts maintained his opinion that Richard Henry Bain acted out of anger over the election outcome when he allegedly opened fire outside the venue hosting the Parti Quebecois victory rally nearly four years ago.

Bain has pleaded not guilty to six charges, including first-degree murder and is arguing he's not criminally responsible by way of mental disorder.

That defence is at the heart of a disagreement between the Crown and defence experts.

The defence expert has told the court she believes Bain had an undiagnosed bipolar disorder and that an overdose of anti-depressants triggered a manic and psychotic episode. 

Watts, a forensic psychiatrist hired by the Crown to assess Bain, concluded he was angry  with Quebec separatists and was not delusional.

The Crown expert says Bain was able to appreciate both the nature and quality of the acts for which he is accused.

The trial marked Day 30 on Monday.
